Looking for some Mac blogging software

A couple of months ago I downloaded Windows Live Writer.  As far as blog publishing tools go, this is the all the blogging software that I need.  I can pick which blog I want, write a post, and then click upload.  Other than editing posts later on (which the software seems to be fairly limited in doing, it's a Live Writer not a Live Editor or Manager), it does what I need.

However, I recently picked up a Mac laptop.  I didn't replace my Windows laptop, I just wanted to have a Mac as well.  Now I need some blogging software for it that is similar to Live Writer.  I need it to be able for me to pick which blog I want to upload to and press Publish to upload it.  That's what Live Writer does, that's what I want my Mac blog software to be able to do at a minimum without having to start a new blog.  I have two; I'm not starting one more.

Anybody have any suggestions?

Edit: I'm viewing the spam traffic analysis post on my Mac as well as my Windows machine.  I had to make the image smaller to make it fit on the screen better so I reduced the dimensions by 25%.  It looks much better on the Mac than in Windows in terms of how grainy and pixelly the image is.
